Marine biologists had hypothesized that lobster kept together in lobster traps eat one another in response to hunger. Periodic checking of lobster traps, however, has revealed instances of lobsters sharing traps together for weeks. Eight lobsters even shared trap together for two months without eating one another. The marine biologistsтАЩ hypothesis, therefore , is clearly wrong.
The argument against the marine biologistsтАЩ hypothesis is based on which one of the following assumptions
Lobsters not caught in lobster traps have been observed eating one another
Two months is the longest known period during which eight or more lobsters have been trapped together
It is unusual to find as many as eight lobsters caught together in one single trap
Members of the other marine species sometimes eat their own kind when no other food sources are available
Any food that the eight lobsters in the trap might have obtained was not enough to ward off hunger
